Dice Coefficient

The Dice Coefficient is a measure used to compare how similar two sets or groups are, often in image or data analysis. It calculates the overlap between them as a ratio. Imagine two circles representing different groups; the Dice Coefficient considers the size of their common area relative to the total size of both circles. Values range from 0 (no overlap) to 1 (perfect match). It helps assess accuracy or similarity, especially useful in tasks like image segmentation, by quantifying how well one set matches another.
